DESCRIPTION:Biological systems\, from individual biomolecules to entire org
 anisms\, naturally generate electrical and electromagnetic signals. The fi
 rst part of the lecture will focus on the frequency bands in which this ac
 tivity has already been thoroughly explored\, and on those where current k
 nowledge is still limited. Special attention will be given to the visible 
 spectrum\, in which practically all organisms emit weak but measurable che
 miluminescent signals. An overview will be provided on the use of intense 
 pulsed electric fields (PEF) in biological systems.\n\nIn today’s societ
 y\, which is increasingly focused on sustainability and environmental prot
 ection\, it is essential to thoroughly analyze and assess the ecological f
 ootprint of various sectors\, including transportation. Personal automobil
 es represent a significant source of environmental burden\, with their eco
 logical footprint encompassing not only greenhouse gas (GHG) emissions dur
 ing operation but also the environmental impacts associated with their pro
 duction\, maintenance\, and disposal. Determining the ecological footprint
  of vehicles is a key tool for evaluating the environmental impacts of aut
 omotive transport.\n\nThe current state of energy demand fulfillment is un
 sustainable\; therefore\, global organizations and companies are striving 
 to prepare for the necessary transformation of energy sources. Over the pa
 st decade\, the cost of producing photovoltaic solar cells has significant
 ly decreased while their efficiency has considerably increased\, making th
 is type of module dominant in the market. Photovoltaics is thus becoming a
  very important source of electrical energy. As a result\, the number of i
 nstalled photovoltaic power plants worldwide—and in recent years also in
  the Czech Republic—is growing exponentially.\n\nFuel cells are systems 
 that convert the chemical energy of electroactive materials directly into 
 electric current. Theoretically\, cells can operate indefinitely because t
 he electrodes do not participate in the chemical reaction. The function of
  the electrodes in the electrochemical reaction of these systems is purely
  catalytic\, which is the main difference compared to primary and secondar
 y sources. The basic principles of the most significant and promising type
 s of fuel cells will be described.\n\nAnother lecture will address the fie
 ld of 3D printing and its use in the design and production of antenna lens
 es with spatial distribution of effective permittivity\, which are based o
 n so-called artificial materials. During the lecture\, the advantages and 
 disadvantages of this approach compared to conventional implementation met
 hods will be discussed. Applications of these lenses will be demonstrated 
 for improving the parameters of chipless identification tags in passive in
 door localization\, and for lens antennas with wide-angle beam steering ca
 pability in the millimeter wave band up to 110 GHz.\n\nThe differences bet
 ween surveillance and meteorological radars will be described\, the radar 
 equation in meteorology will be derived\, and it will be explained how the
  effective radar cross-section of meteorological targets is calculated and
  which quantities are used in radar meteorology\, including their transfor
 mation into frequency-independent quantities. Subsequently\, specific rada
 r measurements by IAP radars located at the Milešovka meteorological obse
 rvatory (837 m) will be described. These operate in the X-band (9.5 GHz) a
 nd the Ka-band (in our case\, 35 GHz).\n\nWith the rise of electromobility
  and battery storage systems\, the issue of accurate and fast evaluation o
 f the current state and lifetime prediction of battery cells is gaining pr
 ominence. One way to obtain detailed information about processes inside th
 e battery is Electrochemical Impedance Spectroscopy (EIS). Compared to con
 ventional methods\, its main advantages include speed and the amount of in
 formation it provides—for example\, in comparison with capacity testing 
 and internal resistance measurements.\n\nTake advantage of this exceptiona
 l opportunity to meet with colleagues working in the field\, establish\, r
 enew\, or deepen personal or professional connections. We look forward to 
 meeting you and cordially invite you to attend the seminar with an accompa
 nying exhibition of products from companies operating in the field of high
 -frequency and microwave technology.\n\nAgenda: \n8:00 – 9:00 Registrati
